To all whom it may concern: I

Be it lmownthat I, RAsMUs Jensen, a citizen of the United States, residlng atjLos have invented a new and which the followmgiis a specification. The primary object of this inventron 1s to provide an automatic water vaporizer for carburetors which will supply a proper mixture of air and water to the mixing chamber of the carbureter, and which automatically varies the relative proportions of air and moisture as the to operate most e ciently. Another object ofjthe invention'is to providea water vaporizer of this nature having a thermostatically controlled water regulating .val e.

Another, an no'less important, object of the invention is to provide in a carburetor water vaporizer a gravity air valve which operates to open a water inlet valve in such wise that the amount of water obtained is directly proportional to the amount of air.

With these and other objects in view, the invention consists in certain novel features of construction; combination and arrangement of parts as will be hereinafter fully described, illustrated and claimed. I

The drawing is a longitudinal sectional View partly in elevation through the preferred embodiment of my water vaporizer.

Referring in detail to the drawing by numerals, 1 designates as an entiret the body casting which, as shown, is prefera Ely formed with a hollow interior providing a mixing chamber 2 and an outlet passage 3, the exterior wall of which is formed with a pipe thread 4 to make a screw connection with the mixing chamber of a carbureter, not shown.

An opening 5 is formed in the bottom of the casting communicant with the mixing chamber 2 and in this opening'is threadedly secured valve cage 6, having ports 7 and a central sleeve 8, which slidingly receives the stem 9 of a suction operated air valve 10. The upper portion 11 of the valve 10 is of frusto-conical formation, and the lower portion 12 is beveled downwardly and inwardly to form an inverted frusto-conical conformation. The beveled portion 12 seats against the corresponding beveled face 13 of the valve cage.

the body casting I is formed with a port 1 opening into a chamber 15 formed by an in- "te'rnally threaded boss or sleeve 16. The port 13 is of less diameter than the interior of the sleeve '16, and soa seat for the valve 17 is provided. This valve has an inverted frustobore '19 formed in an adjusting screw 20. The adjusting screw threads into the chamber 15 and bears against one end of the helical spring 21, the other end of said spring resting upon the top of the valve 17.

A-rearwardly extending passage 22 con- An inclined nipple 24: having a bore 25 connecting with the passage 22is provided for connection to a Water source.

The valve 23 is thermostatically operated by the'thermostat26 preferably formed of a steel 'strip 27 and; a copper strip 28. 'The thermostat is bent intothe form of an open loop','one end of which is connected to the casing by a screw 29, and'the other end of which is formed with a threaded opening through which extends the valve 23, said valve being threaded for a portion of its length to engagelthe threads of the opening in the thermostat. 28 indicates a nipple opening in the top of the mixing chamber 2 and being designed for connection with a moist air supply'such as the radiator of an engine.-

When starting a motor cold, the thermostat 27 is contracted, and the valve 23 seated so that no water may flow through the bypass 24 into the chamber 15. When the'motor speeds up the air intake valve 10 is raised from its seat a distance directly proportional to the speed of the engine, thus admitting air through ports 7 into the mixing chamber 2. After the valve 10 has raised but a slight distance, it engages the valve 17, lifting the latter upwardly and opening the port 23, so that communication between the mixing chamber 2 and bypass 24 is established. As soon as the motor warms up, the heat radiated afl'ects the ther mostat 26, causing it to expand and unseat the needle valve 23, the degree of movement of the valve being directly proportional to the heat radiated. This heat is proportional upwardly.

nects at its inner end with the lower portion to the speed of the engine. When the valve 23 is unseated, water flows into the chamber 15 and then into the mixing chamber 2 onto the top portion of the valve 10. The inrushing air coming through the ports 9 strikes the water tearing it'from the surface of the valve and thoroughly atomizing it. The faster the engine is run, the wider the valves 10 and 23 will open, and the more of gravity and heat will be generated, causing the thermostat to expand greatly. and admit sufficient water to keep the engine, from overheating under heavy working strain. When the engine is running slow with a light load, valves 10 and 23 remain closed through the force the tension of the. spring 21 respectively, and no moist air is supplied through the nipple 28 which latter is always in open communication with the in-v terior of the casting.

From the foregoing description, taken in connection wit the accompanying draw ings, it will be apparent that I have provided a very simple and practical water a body designed to be connected to the intake of an explosive engine and having an air outlet passage and an air inlet port, a valve between said pas sage and port, a fluid supply port communieating with the passage, and a valve for the fluid supply port operated to open by movement of the air admission valve.

2. In combination, a body designed to be connected to the intake of an explosive engine andhaving an air outlet passage an an air inlet port, a valve operated to open by suction of the engine, a fluid supply port communicating with the passage, and a valve for the fluid supply port operated to open by opening of the air admission valve. 3. In combination, a body designed to be connected to the intake of an explosive engine and having an air outlet passage and an air inlet port, a valve between said passage and port, a fluid supply port communicating with the passage, a second valve to control said fluid supply'port, and a thermostatmounted on the body and connected to the second valve to automatically regulate the degree of openingot' the said second I valve.

4. In combination, a body designed to be connected to the intake of an explosive .en- 'gine and having an air outlet passage and an air inlet port, a valve between said passage and port, a fluid supply port communicating with said passage, a second valve for the fluid supply port operated to open by movement of the air admlssion valve, a bypass communicating with the fluid supply port, a third valve for said by-pass, and a thermostat mounted on the body and connected to the'third valve to automatically regulate the degree of opening of said third In testimony whereof, I have hereunto set my hand at Los Ange-les, California, this 2nd day of October 1914.
